system halts

[johnnybwoy]

all,

hopefully one of you here can help me out.

my setup:
- MSI K7T Pro2-a
- AMD Athlon 1GHZ
- 512 133mhz ram
- nvidia geforce 2mx 64mb
- creative sb live

my system will freeze randomly could be on for 30 mins. to 12 hours. no display on the monitor (black screen). no keyboard/mouse response. HDD light steady on. Only way to recover the machine is reboot via power button.

I have determined that it is not the OS (running both linux & XP), not the hard drive, I have two hard drives. Not the video card, have tried three cards. Have tried two power supplies (but same model). I have done a memory test and come up with no errors. Also ran a HOT CPU demo version test CPU passed. Any suggestions appreciated. Thx.

:frown:

You could have one intermittant component, from your power supply to your vid card or any other plugin card, to your RAM, or a single component (chip, resistor, etc.) on your motherboard. The only way I can think of to isolate it is to swap things out, one at a time.
